Application April 26, 1955, Serial No. 503,975

1 Claim. (Cl. 16-161) The present invention relates to an oilingattachment for hinges and it consists in the combinations, constructionsand arrangements of parts herein described and claimed.

Generally there is provided an attachment for a hinge consisting of acylindrical oil container having an open top and a bottom which isapertured to receive therethrough the body of a pintle, the head of thepintle being adapted to be received within the container. A plurality ofcircumferentially spaced relatively small notches extend radially fromthe pintle receiving aperture. A cap for the container completes thedevice and the device is such that it may be quickly and easily mountedupon the conventional hinge pintle and provided with a few drops of oilwhich will thereafter be fed by gravity and capillary attraction downupon the outer face of the body of the pintle thus effecting a saving ofoil and at the same time providing a means for maintaining a hinge inconstantly lubricated condition.

It is accordingly an object of the invention to provide a novel oilingattachment for hinges.

Another object of the invention is to provide a device of the characterset forth which is simple in construction, inexpensive to manufactureand yet effective and efiicient in use.

A further object of the invention is to provide, in a device of thecharacter set forth, novel means for feeding oil to a hingeconstruction.

Another object of the invention is to provide, in a device of thecharacter set forth, novel means for storing a lubricant.

Other and further objects of the invention will become apparent from areading of the following specification taken in conjunction with thedrawing, in which:

Figure 1 is an elevational view of a hinge showing an embodiment of thepresent invention mounted thereon,

Figure 2 is an enlarged fragmentary view, partly in section,illustrating an embodiment of the invention mounted upon a hinge,

Figure 3 is a sectional view taken along line 3-3 of Figure 2,

Figure 4 is a vertical sectional view of a cap forming a part of theinvention,

"ice

Figure 5 is a vertical sectional view of a container forming a part ofthe invention, and

Figure 6 is a sectional view taken along line 66 of Figure 5.

Referring more particularly to the drawing, there is shown therein ahinge structure including a pair of hinge plates 10 each provided Withconventional pintle bearings 11 through which extends in conventionalmanner a pintle 12 provided at its upper end with the conventional head13.

The device of the present invention consists of an open toppedcylindrical container 14 provided in its bottom wall with a centrallydisposed circular opening 15 from which extends radially a plurality ofrelatively small notches 16. A cylindrical cap 17 completes the device.

In use, it will be apparent that the pintle 12 is first inserted throughthe aperture 15 in the container 14 and then positioned in the pintlebearings 11 in customary manner. It will also be understood that theopening 15 is of such size as to snugly fit against the outer surface ofthe pintle 12. A few drops of oil may then be placed in the container 14and will then flow by gravity and capillary attraction through thenotches 16 downwardly upon the face of the pintle 12 to therebylubricate the interior of the bearings 11 in their contact with thepintle 12. The cap 17 snugly fits over the container 14 to thus preventdust and the like from entering therein. Thus it will be seen that thedevice may be filled only on rare occasions and that it will thenmaintain for long periods of time a hinge in proper lubricatedcondition.

While but one form of the invention has been shown and described herein,it will be readily apparent to those skilled in the art that many minormodifications may be made without departing from the spirit of theinvention or the scope of the appended claim.

What is claimed is:

In combination with a hinge structure including a pintle having a shankand a head at the upper end of said shank, an oiling attachment for saidhinge structure comprising an open-toped cylindrical member encompassingsaid head and having a centrally disposed aperture in the bottom thereoffor receiving said shank therethrough, and a cap removably mounted onthe upper end of said cylindrical member, said aperture having aplurality of relatively small circumferentially spaced radiallyextending grooves extending outwardly therefrom.
